ICEdot Crash Sensor

The ICEdot Crash Sensor is a really great concept for riders how find they are doing a lot of riding by themselves, either on unfamiliar trails or outside the busy times on their local trails and want some peace of mind. So we got Richard Pieterse to give it a through test.

I had some issues with the initial Crash Sensor.  At first I thought I was technically challenged or, as my wife put it, a bloke ‘who thinks he does not need to read the instructions’ as this is so basic anyone can set it up…  A quick call to Patrick Cawood and his team, and some remote fault finding to ascertain if it was a device issue or the bloke behind the device, revealed I didn’t have to read the instructions.  Patrick and his team were on the ball and replaced the faulty unit with a new one, and have been great in following up to check if all is still ok. So the back-up support is excellent, thanks Patrick.

How it works:

The Crash Sensor device itself is a small compact unit that one mounts on ones helmet using cable ties and is paired via Bluetooth 4.0 with your smartphone. So make sure your phone is equipped with the Bluetooth 4.0.

The basic concept is that the Crash Sensor can detect motion, changes in force and impact, so in the event of an impact, the sensor will trigger the smartphone via low energy Bluetooth, which in turns sounds an alarm and activates an emergency countdown. Unless the countdown clock is stopped, the app will then notify your emergency contacts, sending a pre-defined message created when you set-up your ICEdot profile, plus more importantly, your GPS co-ordinates on a Google Map.

Getting Started:

This is a simple process whereby you create an ICEdot ID profile by activating the PIN code found on your ICEdot product by following the instructions on

The ICEdot profile allows one to share information such as who you are, medical aid, doctor’s details, medications or allergies and how to reach your emergency contacts. It also allows you to set-up a list of emergency contacts that will be notified by SMS with your location and relevant personal and medical information.


ICEdot membership is R100 per year, per person.  Each product, there are also ICEdot Bands and ICEdot sticker packs for those only looking to load an emergency ID profile, comes with a one year membership included. So, in essence, your first year is free.

ICEdot App:

The app is available for free on the App Store. Search for ICEdot and download.  Be careful as there is a similar app ‘ICEdot Medic’ which is not the correct one.

Device Support:

The Crash Sensor app is currently only supported on iPhones 4S and later and an Android version is available for Nexus 4 and 5 phones (Google). There are some apps for other Android devices running 4.3 or later but these are considered public beta (the third phase of testing).

Currently there is, unfortunately, no support for any Samsung phones. The reason for this is that sensor requires Low Energy Bluetooth to communicate with the phone and at present Samsung does not use Google’s code for this so it won’t work at all until they implement the full code from Google.

I am also using the ICEdot silicone arm band.  This has a PIN etched into this silicone bracelet, which can be used to identify you and notify your emergency contacts. Currently there are only US and EU emergency contact numbers, but there is a South African number in the pipeline for mid-2014. The first responder will simply SMS the PIN to either number on the band and they will receive an SMS with your profile plus a short URL that will provide access to your personal and medical information.  The fact that the emergency contact number is an international number could potentially be an issue for some people, but it is only SMS fee.
